The EMBRACE System Demonstrator

Within the EMBRACE project an advanced communications system and network was developed. It uses the DVB technology for the high-speed downlink and a novel multi-frequency TDMA system for the return link. The return link is scaleable to accommodate the variety of data rates. Emphasis was put on providing quality of service (QoS) in wireless IP networks. Site diversity is used to increase the availability of this 42GHz system. Efficient synchronisation between the DVB forward and the MF-TDMA return channel was implemented. The system supports bandwidth on demand and efficient utilisation of capacity and was successfully demonstrated at the IBC 2001 in Amsterdam. The user can access broadband services, such as fast Internet, near video-on-demand, broadcast video, video streaming, video conferencing and voice over IP. An advantage is the fast set-up of the equipment.
